WebMolecular Weight: 520.39 PyBOP is an efficient coupling reagent utilized in solid phase peptide synthesis. It has reactivity similar to BOP, but its byproduct is not highly carcinogenic. PyBOP was utilized in the solid-phase synthesis of the tetrapeptide H-Ile-Ala-Leu-Pro-OH on 2-chlorotrityl resin. WebOne of the strategies is to use a coupling agent such as DCC (N,N’-dicyclohexane carbodiimide) or EDC (1-Ethyl-3- (3-dimethylaminopropyl)carbodiimide. Both are carbamides (RN=C=NR) which prevent the acid-base reaction and make the carboxylic acid susceptible to a nucleophilic attack. trw reamer
